Serial No. 398,867.

To all whom it may concern:

Be it known that I, CHARLES A. LIND- s'rRoM, of Allegheny, Allegheny county, Pennsylvania, have invented a new and useful Journal-Box, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a longitudinal vertical section of my improved journal box; Fig. 2 is a partial cross-section on the line IIII of Fig. 1; Fig. 3 is a vertical cross-section, the left-hand half being through the securing bolt sockets, and the right-hand half in front thereof and Fig. 4: is a partial crosssection on the line IV-IV of Fig. 3.

My invention relates to the class of j ournal boxes of the type known as Master Car Builders standard, and is designed to provide an improved structure in which the oil and waste will be distributed to the best advantage, that is, avoid unnecessary space, where it is of no benefit, and provide increased space where lubrication will be improved by a larger quantity of waste and oil than has been possible to use heretofore.

A further object of the present invention is to properly locate a suitable line of ridges or projections, on the bottom of the box and separated from each other at their bases by wide spaces open from the box bottom to the top of the projections to prevent the carrying around of the waste bodily as the journal revolves, while allowing free channels for the oil to flow over the box' bottom from one side to the other to saturate the waste at both sides of the journal, and allowing wide transverse spaces for the waste, intersecting the said line of ridges or projections, so that the waste body is practically continuous beneath the journal, from one side of the journal box to the other. As shown in the drawings, the said line of ridges or projections extends longitudinally of the axle in the vertical plane of the journal axis.

In accordance with my invention, the ridges or projections on the bottom of the box, just referred to, are arranged in a central line along the bottom of the box so as not to interfere with the packing of the waste in the box on either side thereof. These projections are tapered and separated from the bases to tops by spaces for the purpose of allowing a free circu1ati0n 0f the oil from one side of the box to the other across the box bottom.

It is well known to those familiar with the Master Car Builders standards for journal boxes, that in order to facilitate interchangeability there is a fixed distance between the bolts which secure the journal boxes to the truck frames. This distance is such that if the side Walls of the box are carried down perpendicular from the top to near the bottom, the space for waste and oil near the sides of the journal is very limited. To overcome this I bulge the side walls outwardly from a point at about the lower edges of the journal bearings at which point the first contact is made by the waste and oil with the journal. This outward bulging is made both at the front and back of the bolts, so that the only narrow space remaining is immediately opposite each bolt where it is impossible to provide greater space. This method provides all around the exposed part of the journal a space of almost uniform depth for the packing of the waste and the reception of the oil. The waste and oil are not massed in the bottom where they will fall away from the journal and be useless, but are well distributed around the bearingportion. The greater volume of waste on the sides is more elastic than the former thin layers in these portions, and will hold more oil by its capillary attraction. At the same time in order to make the box of substantially the same volume as that of the ordinary M. G. B. type, and to prevent the waste collecting in a useless portion of the box, I incline the front wall from a point at or near the lower part of the lid downwardly and backwardly to join the bottom. The volume of the box is therefore substantially the same as before, while the oil and waste are distributed so as to give a muchmore eflicient action.

In the drawing, I show a cast journal box, though it may be'madein any desirable way, the casting having its side walls 2 bulged outwardly both in front of and in erably extended downwardly from about the line aa to bring its lower surface into sure will be exerted on the tie bar as well as on the journal box, thus avoiding undue strain on the journal box itself. In order to lighten this part of the casting, which would otherwise be so thick as to increase the weight, I preferably form pockets 5, these pockets being divided by a central longitudinal rib or upward projection 6. This projection preferably joins the bottom with the front wall and strengthens this front wall.

In line with the ridge or projection 6, I preferably employ one or more separated projections or ridges 7 and 8, which leave cross channels between them fo-rthe passage of the oil and distribution of the waste. Atthe same time excessive carrying around of the waste is prevented by the ridges or projections; while the rear projection unites the rear and bottom walls and strengthens the casting. These projections extend longitudinally of the journal and in a line in the vertical plane of the journal axis, the spaces between the same providing the transverse passageways or cross channels referred to.

, The advantage of my invention will be apparent to those skilled in the art. The cubic contents of the box may be substantially the same as that of the usual box of the M. O. B. type, while, owing to the outwardly bulged side walls and the downwardly and inwardly inclined front wall, a more effective action is obtained for the oil and waste, which is more evenly distributed and gives a more efficient action. The downward and inward curved lines of the sides from the bulged portions transmit the lifting strains more directly to the side walls, and the jacking-up pressure is applied not only to the lowered front portion of the bottom, but

also to the tie bar at the same level. The

bottom pockets lighten the casting and prevent its being heavier than desirable, while they receive oil and waste below the journal. The separated central longitudinal ridges or projections on the bottom, give free channels for the oil while preventing carrying around of the waste. By placing these ridges in the centerv of the box and directly below the axis of the journal, they give the least obstruction to the packing of the waste by means of a rod extending through the front of the box. The front and rear projections also connect the rearand front walls with the bottom and strengthen them'a'gainst breakage.

I claim 1. A journal box having a portion of its bottom depressed to form a pocket and a jacking surface with a rib extending across said depressed portion to strengthen said jacking surface.

2-. A journal box having an abrupt depression in its bottom wit-h a reinforcing rib extending across said depression.

3. A journal box having an abrupt depression in its bottom and a reinforcing rib extending across said depression and upwardly above the box bottom to retard waste.

4. A journal box having its side walls bulged outwardly in a curved line in front and rear and having along its bottom a plurality of projections extending in a linelongitudinally of the axle in the vertical plane of the journal axis, said projections being separated'from each other at their bases by a wide space open from the box bottom to the top of said projections, to provide a free channel for transverse passage of oil over the box bottom and a transverse space for waste intersecting the said line of projections. 7

5. A journal box having its side walls bulged outwardly in the front and rear and a plurality of projections extending longitudinally of the box in the vertical plane of the journal axis and separated from each other at their bases by a wide space open from the box bottom to the top of said projections to provide a free channel for transverse pas-- sage of oil over the box bottom and a trans- 1 verse space for waste intersecting the line of projections and in the same plane therewith ;v

said box also having an abrupt depression in the forward portion of its bottom.

A journal box, having journal box bolt seats at its sides which are at the standard distance from each other, and having its side walls bulged outwardly both in front of and at the rear of said seats, the bottom wall of the box being depressed at its front portion to form a pocket, and the bulging side walls converging inwardly to the bottom of said pocket; substantially as described.

In testimony whereof, I have hereunto set my hand. 7
